However, in certain circumstances, the Court may use temporary staff or contract staff for auxiliary tasks. Temporary staff are engaged principally to occupy posts which will ultimately be filled by successful competition candidates. They may occupy posts which require a specific profile for short assignments. Contract staff for auxiliary tasks replace officials prevented from performing their duties because of illness or who are absent on maternity leave. They are also engaged in order to reinforce a department which has to cope with an unusually high volume of work.

Staff are divided into two categories: function group AD which includes administrators and lawyer linguists and function group AST which includes administrative assistants. Function group AD requires a university degree, or its equivalent, while function group AST requires at least a level of post-secondary education or a level of advanced secondary education and three years' professional experience.

The Court recruits most frequently staff for the following professions:

For function group AD:

Legal administrator in a registry or in the fields of library services, research and documentation

interpreters

lawyer linguists for the translation of legal documents from two official languages of the European Union

Candidates are advised to use the ‘Europass' format (see http://europass.cedefop.europa.eu/) in order to submit their CV. The spontaneous applications sent in are kept for two years and may be considered when a suitable vacancy arises.
